BACKGROUND Detailed anatomy of the anterior commissure is unknown in the literature. OBJECTIVE To describe the anterior commissure with the use of a fiber dissection technique by focusing on the morphology (length and breadth of the 2 portions), the course, and the relations with neighboring fasciculi, particularly in the temporal stem. METHODS We dissected 8 previously frozen, formalin-fix...

BACKGROUND Modalities of surgical treatment of early glottic carcinoma include transoral laser microresection and external partial surgery. METHODS This is a retrospective analysis of 119 glottic carcinomas treated by external partial surgery (57 pT1a, 1 pT1b, 10 pT2) or transoral laser microresection (46 pT1a, 4 pT1b, 1 pT2) with special regard to initial anterior commissure involvement. R...

The anterior commissure is an evolutionarily conserved nerve bundle that connects the right and left hemispheres, playing pivotal neurological roles in visual, linguistic, and olfactory functions. The authors herein describe a 16-month-old boy with high fever, lethargy, and recurrent seizures. Polymerase chain reaction (PCR) examination detected human herpesvirus 6 (HHV-6) in both the cerebrosp...

OBJECTIVE To analyze the impact of anterior commissure involvement on rates of local control, recurrence, and laryngeal preservation in patients with early glottic cancer (T1a-T2 lesions, staged according to the TNM staging system) treated with laser microsurgical resection. DESIGN Retrospective review. SETTING A tertiary university referral center. PATIENTS Forty-eight patients with earl...

Earlier studies have shown that the corpus callosum of rats tends to be larger in males than in females. We report here that the anterior commissure of rats is also larger in males than in females. The sizes of the two commissures were positively correlated in both sexes, but significantly more so in females than in males. The anterior commissure size difference in rats reported here is opposit...

Treatment of glottic carcinoma with anterior commissure involvement is under debate. Treatment spectrum includes surgery, open or endoscopic, and radiotherapy. Since similar results are reported in the literature, preferences depend on experience and skill of the person responsible for treatment. Our objective is the analysis of scientific data published in Medline, CancerLit, Cochrane Register...

BACKGROUND AND PURPOSE Agenesis of the corpus callosum, even when isolated, may be characterized by anatomic variability. The aim of this study was to describe the types of other forebrain commissures in a large cohort of randomly enrolled fetuses with apparently isolated agenesis of the corpus callosum at prenatal MR imaging. MATERIALS AND METHODS All fetuses with apparent isolated agenesis ...

The full extent of the cortical field of origin of the anterior commissure of the rhesus monkey was mapped by horseradishperoxidase (HRP) histochemistry. Two adult monkeys were first subjected to complete callosal commissurotomies and permitted to fully recover 6 months prior to a second operation involving the massive unilateral injection of HRP into the entire left temporal lobe. Because the ...

Acoel worms are simple, often microscopic animals with direct development, a multiciliated epidermis, a statocyst, and a digestive parenchyma instead of a gut epithelium. Morphological characters of acoels have been notoriously difficult to interpret due to their relative scarcity. The nervous system is one of the most accessible and widely used comparative features in acoels, which have a so-c...
